South Africa's Colin Nel went into the second round of the Nelson Mandela Championship facing an early exit after shooting an opening seven-over 77 and finished it by achieving one of golf's most elusive feats -- a round of 59.

It catapulted Nel up the leaderboard from 138th into the top 20 but astonishingly his score was also matched Friday by Jorge Campillo of Spain.

Campillo improved a mere 11 shots on his opening level-par 70 to be one behind leader Daniel Brooks when play was halted.

England's Brooks shot a 62 in his opening round and was through 11 holes of his second at 12-under. The European Tour event has been reduced to 54 holes after being hit by thunderstorms and heavy rain.

That also had implications for Nel and Campillo as their scores will not count for the record books because players were allowed to use preferred lies on the rain-sodden fairways at Mount Edgecombe.
